Cilostazol is used to improve the symptoms of a certain blood flow problem in the legs (intermittent claudication). Cilostazol can decrease the muscle pain/cramps that occur during exercise/walking. Claudication pain is caused by too little oxygen getting to the muscles. Cilostazol can increase blood flow and the amount of oxygen that gets to the muscles. Cilostazol is an antiplatelet drug and a vasodilator. It works by stopping blood cells called platelets from sticking together and prevents them from forming harmful clots. It also widens blood vessels in the legs. Cilostazol helps the blood to move more easily and keeps blood flowing smoothly in your body.
